I have a BA in Mathematics. The limit is indeed determined by the direction you approach the limiting value.
When given without specification, the limit is implied to come from the left, meaning it increases towards the limiting value, which is why you see +inf.
It’s been a while… but isn’t that negative?
Or is there some default given of which side it’s approaching from.

Yeah but then it should be negative infinite, cause if x<8 the fraction is negative.
I think it is not defined. It has a limes from the left (- inf) and limes from the right (+ inf) but no two-sided limes.
Edit: wolframalpha agrees but I don’t know for sure
Is that the Tootsie Roll Theorem?
You put the lime on the coconut and drink it all up.
It should be +/-∞
Minus or plus depending on the side from which you approach the limes.
Infinity limes? After all these years, this meme starts to make sense:
